COCK AND VALVE.

SPECIFICATION forming part of Letters Patent No. 273,62,-dated March 1?,1883.

(No model.)

1'0 all 'lU/LOHL it may concern:

Be it known that we, TIMOTHY l). Lyons and DANIEL J. LINEHAN, bothcitizens of the United States, residing at Brooklyn, in the 5 county ofKings and State of New York, have invented new and useful Im prorementsin Cocks and Valves, of which the following is a specification.

This invention relates to improvcmeutsin that; class of cocks or faucetsthe valve-stem or which can be covered and concealed by a screw-capadapted to a screw-thread surrounding the stem for the purpose ofpreventing unauthorized persons from opening the cock or faucet unlessthey resort to a wrench or other implement to remove the cap.

The object of our invention is to'provide means for concealing andprotecting the screwthread around the valve-stem in order to reuntil itis desired to screw the cap thereon.

To this end our invention consists in acock orfa-ucet having ascrew-thread surrounding its vavle-stem, combined with a ring having aninternal screw-thread ot'awidth approximately equal to the saidscrew-thread around the valvestem, and adapted to be screwed thereon toconceal and protect the same until it is desired to apply the cap forcovering the end of the valve-stem.

in the accompanying drawings, which illustrate our invention, Figure 1represents a twoway cock with the cap in position; Fig. 2, a detachedsectional view of the ring which serves to conceal and protect thescrew-thread around the valve-stem when the cap is removed; Fig. 3, aView showing the ring in position; and Figs land 5represenflrespectively, caps applied to screw-threads on the valvestemitself, and on a screw-threaded neck of the casing.

The cook or faucet may be of any known construction, with a Valve-stem,G, for opening and closing the valve which controls the usualpassage-way through the valve. The annular screw-threads F, (shown inFigs. 1 and tain said thread clean and in good condition 3,) forreceiving the intcrnallythreaded cap A, are formed on the casingof thecook or faucet, so as to surround the valve-stem,while in Fig. 4: thescrew is on the valve-stem itself, and in 0 Fig. 5 the screw-thread ison a neck projecting from the casing. In all the constructions shown theinternally-ti]readed cap is adapted to the screw-threads F, for thepurposeof covering and concealing the valve-stem G for the purpose ofrendering it impossible to operate the stem to open the cock or faucetwithout first removing the cap through the medium oi a wrench or otherimplement.

When the cap is not in use on the cook or faucet it is desirable toconceal and protect the screw-threads F, for the purpose of preventinginjury to them and their becoming clogged with dirt, and to retain suchthreads in the best condition to conveniently apply the 6 cap A whendesired. To such end we provide a ring, B, which is internallyscrew-threaded, and is of a width equal or approximately equal to theheight of the screw-threaded portion on the cook or faucet or itsvalve-stein, such ring being ada ted to screw on such screwthreads andthereby accomplish the object stated.

We do not broadly claim the screw-thread on the casingot' the cook orfaucet or its valve, 7 nor do we claim a cap adapted thereto; but,

Having thus described our invention, what we do claim is- A cook orfaucet having a screw-thread sun rounding its valve-stem, combined withthe ring B, having an internal screw-thread of a width approximatelyequal to the screw around the valve-stem, substantially as and for thepurpose described.

In testimony whereof we have hereunto set 8 our hands and seals in thepresence of two subscribing witnesses.
